TYPE-WRITING MACHINE.

Specification of Letters Patent.

Patented Dec. 30,1913.

Application filed February 10, 1908. Serial No. 415,210.

To all whom 'it may concern:

- Be it known that I, HENRY W. Mnnnrrr, citizen of the United States, and resident of Syracuse, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in Type- Writing Machines, of which the following is a specification.

My invention relates to typewriting machines and more particularly to billing mechanism and it is especially adapted for use in condensed record billing work.

1 The main object of the invention is to provide mechanical means for accurately limiting the rotation of the platen to the extent required for condensed record work.

detail sectional view taken centrally through the platen and longitudinally thereof. Fig.

2 is an enlarged detail fragmentary plan view showing oneend of the platen and the billing devices associated therewith. Fig. 3 is an end view of the carriage with parts broken and sectioned away.

I have shown my invention applied to a Monarch typewriting machine, although it should be understood that the invention may be embodied in other styles of typewriting machines whether visible or blind writing machines. l

The top plate 1 vof the machine supports upwardly extending risers 2 to which fixed guide rails 3 are secured by screws 4. The fixed guide rails 3 are grooved at 5 for cooperation with anti-friction balls 6 received in grooves 7 of a rear cross bar of the carriage from the ends of which forwardly extending -end plates 8 project. The carriage is thus supported and guided in its movement across the machine from side to side thereof. The end plates 8 are provided with a bearing for a platen shaft 9 which supports a rotative platen 10. The usual paper feed devices which cooperate with the platen have been omitted, the main feed rollers 11 alone being shown diagrammati-- an indicating mark 27.

cally in Fig. 3. The left-hand platen head 12 is provided with teeth 13 which constitute a line spacing wheel with which a line spacing pawl 14, controlled in the usual manner by a finger piece 15, cooperates. A spring pressed roller detent 16 bears against the crown teeth 13 to retain the platen against accidental displacement. An actuation of the finger piece 15 effects a line spacing movement of the platen in the usual manner.

From an inspect-ion of Fig. 1 it will be seen that an indicating disk 17 is secured by machine screws 18 to the right-hand platen head 19. This disk may be termed an indicating carrier and is provided with a notch or depression 20 in the periphery thereof as shown in F ig. 2 for cooperation with a bent portion 21 (see Figs. 2 and 3) of a spring detent or arm 22 secured by a screw 23 to a forwardly extending lug or projection 24 on the rear cross bar of the car riage. A second indicating disk or carrier :25 is mounted beside the indicating disk 17 and is provided with a peripheral flange 26 at one side thereof. .This indicating disk 25. has two notches 27 and 28 in the periphery thereof, said notches being spaced apart as indicated in Fig. 3, and the disk is also provided on the periphery thereof with The left-hand face of the indicating disk 25 bears against the right-hand face of the indicating disk 17 as shown in Fig. 1 and both of these disks 1'? and 25 are mounted concentrically with the platen on a sleeve 29 which projects outwardly from the right-hand platen head 19. The disk 25 is adapted to turn freely on the sleeve 29 in order to afford an adjustment of the disk 25 relatively to the disk 17 and to the platen for purposes which will hereinafter more clearly appear. The sleeve 29 to the right of the disk 25 is threaded as indicated at 30 for cot'iperation with a tapped opening in a disk 31 slightly greater in diameter than the disks 17 and and provided with a knurled periphery as indicated in Fig. 2 to facilitate turning the disk on the threaded portion of the supporting sleeve 29. The left-hand face 33 of the disk '31 is adapted to bear against the right hand face of the indicating disk 25 and when the locking disk is moved to the left along its threaded support it is effective to bind .the loose indicating disk 25 to the fixed indicating disk 17 so that the disks 17 25 and 31 are locked to the platento 1(r tate therewith. A second spring detent 34 similar to the detent 22 and preferably formed as a part thereof is separated from the detent 22 by the flange 26 and has a projection 35 which bears against the p..- riphery of the indicating disk 25 and is received in the notches or depressions 27 and 28 therein. An eccentric or cam 36 is mounted 011 or formed as a part of a shaft 37 received in a bearing opening in the right-hand end plate 8 of the carriage. A shoulder 38 formed on the shaft bears against the inner side of the right-hand end plate and prevents an outward longitudinal movement of the shaft. The shaft extends through its bearing opening in the end plate to the outer side of the plate where it is squared for cooperation with a squared opening in a finger piece 39 secured to the end of the rock shaft by a screw 40. The can 36 extends beneath the spring detents 22and 34 and said cam in the normal position thereof enables the pressure of the spring detents to be exerted against their cotiperating indicating disks. When, however, the finger piece 39 is moved forward the cam or eccentric bears upwardly against the spring detents and forces the free end portions thereof off the indicating disks.

The purpose of the indicating disks and their associated fixed indicating devices is to provide a predetermined extentof lead of an invoice sheet over the carbon and record sheets, as. will hereinafter more clearly appear, and when these indicating devices are not in use for the purpose stated the finger piece 39 may be moved forwardly to release the pressure of the spring detents on the peripheries of the disks 17 and 25. A fourth disk 41 is mounted on the platen shaft 9 beside the locking disk 31 and bears at its left-hand face against the outer end of the sleeve'29. This disk is secured by a feather 42 to the platen shaft to rotate therewith and has crown teeth 43 near the periphery thereof. This toothed disk constitutes what may be termed a clutch member, engaging device or circular rack which is mounted concentrically with the platen. A pawl engaging device, or clutch member 44 is adapted to engage the teeth 43 of the circular rack at various points along the same, as will presently ap pear. This pawl is carried by and preferably forms a part of an arm 45 which constitutes a stop device or rotative stop and which is provided with a hub-like portion 46 split at 47, the split portion being drawn together by a screw 48 in order to secure the arm or stop to a sleeve 49 received in a hearing opening in the right-hand end plate 8 of the carriage. The right-hand end of'the sleeve is connected to, or has formed as a part thereof, a hand actuated device which, in the present instance, is in the form of a finger wheel 50 by whichthe sleeve and the stop arm 45 carried thereby maybe rotated, these parts being mounted concentrically with the platen. An expansion spring 51 is received between the finger wheel 50 and the right-hand end plate of the carriage and exerts a pressure which tends to force the sleeve 49 outwardly in its bearing opening and to disengage the pawl 44 from the teeth 43 of the circular rack, as shown in Fig. 1. A so-called forward stop device, stop'or pin 52 projects inwardly' from the right.- hand end plate of the carriage as shown in Figs. 2 and 3. A like stop or pin 53; which may be termed a back stop, projects from the carriage and both ofthese pins 52 and 53 extend into the path of the stop arm 45 whether it be engaged with or disengaged from the circular rack so that the pins 52 and 53 limit the back and forth rotative movements of the stop 45 and endwise pressure exerted on the finger wheel 50 against the pressure of the spring 51 will force the pawl 44 into engagement with the teeth 43 of the circular rack so as to lock the rotative stop 45 to the platen and aforward rotation of the platen at this time will bring the stop 45 into contact with the fixed forward stop .52 to arrest the platen in its forward movement. After the platen has been arrested in its forward movement, if pressure is released upon the finger wheel 50 the pawl 44will be disengaged from the circular rack by the spring 51 and the platen is free to receive a continued rotative'movement by either of its usual finger wheels 54 and 55 to any desired extent. independently of the stop devices. A rearward rotation of the platen when the rotative stop is locked thereto will bring-the rotative stop into engagement with the fixed back stop 53, thus arresting the platen in its backward movement.

From an inspection of Fig. 1 it will be seen that the platen shaft 9 .is supported in the bearing opening in the right-hand end bar through the intermediate bearing sleeve 49, whereas the left-hand end of -the platen shaft is supported in a sleeve 56 which is secured in an opening in the left-hand end bar 8 of the carriage by a screw 57.

In the operation of the devices for condensed record work it may be supposed that the fixed stops 52 and 53 have been situated at a suitable distance apart for the particular character of work to be performed or to the particular character of bill or invoice sheets to be employed. If the devices are intended to be used with bill heads of different characters the stop pins 52 and 53 may be made relatively adjustable in any suitable manner, as for instance, by providing a series of circularly arranged openings 53 Concentric with the platen in the right-hand end plate of the carriage for one of the stops; the stop 53 forinstance, so that said stop may receive a circular adjustment relatively to the stop 52. Supposing that the stops 52 and 53 are spaced apart the requisite distance for the particular character of bill heads or invoice sheets to be used, the operator first turns the platen until the notch 20 in the indicating disk 17 is brought into register withthe projection 21 of the spring detent 22 which may be readily observed by the operator when the projection contacts with 'or' snaps into the notch or depression 20. The operator then insertsv an invoice sheet and turns the platen forward so as to bring the proper point on the invoice sheet where the first line of writing is to appear to the printing line. The screw disk or locking device 31 is then loosened in order to free the disk 25 which is then given a circular adjustment to bring the indicating mark 27? thereon into register with the notch 20 in the indicating disk 17 as shown in Fig. 2. The screw disk-is then tightened in order to compel the disk 25 to rotate with the platen. The platen is then given a reverse or backward rotation until the spring detent 34 engages or snaps into the second notch 27 of the two notches (27 and 28) to arrive at the detent 34. The operator then inserts a carbon and record sheet between the invoice sheet and the platen, the carbon sheet of course being interposed between the invoice and record sheets. The platen is then given a forward rotation until the proper point on the invoice sheetvwhere the first line of writing is to appear is brought to the printing line.

It will be found that by the manipulation of the parts in the manner described the invoice sheet has been given a lead over the carbon and record sheets. That is to say, the leading edge of the invoice sheet will extend beyond the leading edges of the carbon and record sheets, and the extent of the lead thus produced is a predetermined extent which always brings the first line of the copy of the first bill on the record sheet a given distance from the top thereof, say for an example, one-half inch. Of course the predetermined extent of lead will depend somewhat upon the character of the hill heads or invoice sheets employed and this may be regulated by varying the position of the indicating mark 27 on the indicating carrier or disk 25. The bill having been brought to the printing line to receive the first line of writing in the manner described, the operator proceeds to Write the bill-and a copy thereof will be reproduced on the record sheet. .sfter the bill is completed the platen is line spaced say three times, to provide a proper spacebetween the last line of the copy reproduced on the record sheet and the first line-of the next succeeding copy. After the platen has been spaced as described the release key for the paper feed devices, such forinstance as the release key usually employed in the Monarch machine, is actuated in order to release the paper feed devices when the invoice sheet may be readily removed without disturbing the carbon and record sheets. The finger wheel 50'is then given a forward rotation in order to bring the rotative stop 45 into contact with the forward stop 52. An endwise pressure is then given the finger wheel to effect an engagement between the pawl 44 and the circular rack, the pawl and rack acting in the nature of two members of a clutch which are thus united to connect the stop 45 to rotate with the platen. Theplatcn.

may then be given a rearward rotation either by turning the finger wheel 50 or turning either of the finger wheels 54, 55 while endwise pressure is maintained on the finger wheel 50. The backward rotation of the piaten continues until it is arrested by the contact of the rotative stop 45 with the fixed back stop 53. Endwise pressure on the finger wheel 50 may then be released and a new invoice sheet introduced into the machine. The endwise pressure may again be effected on the finger wheel 50 to engage the pawl 45 with the circular rack and a forward rotation given the platen until the stop 45 is again brought in contact with the fixed stop 52. The extent of this movement of the stop 45 from the back stop 53 to the forward stop 52 is sufiicient to bring the newly introduced invoice sheet to a position to receive the first line of writing at the proper position thereon and the manipulation of the parts described is effective to properly position the newly introduced invoice sheet with reference to the record sheet. Thus, the first llne of the copy of the newly introduced invoice will appear on the record sheet three line spaces from the last line of the preceding copy, the distance between successive copies on the record sheet de ending on the extent of line spacing given tie platen after each bill is Written.

- In front-strike or visible Writing machines the opera-tor need not reingage the pawl 44 with the circular rack in order to arrest the platen during the forward movement thereof, as in such machines the platen may be turned if desired until the invoice sheet is moved to the pro-per position to receive the first line of writing thereon, the operator being able to observe the position of the sheet without resorting to the stop devices to limitthe forward movement of the platen, although the stop devices may be resorted to in order to mechanically limit the forward rotation whether the devices be employed on visible or blind writers.

It will be understood that the stop devices "voice into the machine with reference to the printing line and with reference to the condensed record sheet; whereas the indicating devices 17, 2 5, etc., are merely employed in the first instance to provide a proper lead for the first invoice sheet over the condensed record and carbon sheets. It will be understood therefore that these two sets of devices may be used either together or separately as desired and that the indicating devices for determining the extent of lead to be provided may be employed'in connection with other characters of billing mechanism.

It will be observed that the stop devices of my invention are simple in construction and efiicieut in operation and provide means by which the platen may be turned through predetermined arcs in both the forward and rearward movements thereof and that the platen may rotate independently of the stop devices after the platen has been arrested by the stop devices and that the platen is effective to move a sheetforward from the point where it is introduced into the machine at the feed rollers 11 to the printing line and vice versa and that the stop devices are effective to mechanically limit the platen in these movements and to afford a continued movement of the platen after it" is arrested.

When I refer herein to mechanically coactmg means for giving an invoice sheet a predetermined extentof lead and for determin-- ing the extent of such lead, I employ these, and like terms,to distinguish from constructions in which, for example, visual indicating means are employed to determine the extent of lead.-

I am aware that various changes maybe made in the construction without departing from the spirit of my invention, and I do not therefore limit myself to the details of'the construction shown and described.
